More residential development sites are hitting the market in San Francisco’s hot South of Market district.

Two unentitled parcels at 360 5th St. and and 399 5th St. are now on the market and together could accommodate up to 200 units of housing on approximately half an acre and a quarter acre respectively. The property, however, does not yet have entitlements.

The properties sit in the heart of SoMa and are one block away from where the Central Subway will run when it opens in 2019.

Land prices in San Francisco have escalated over the past few years as more developers compete to snap up increasingly rare sites, many of which are unentitled.

A marketing brochure for the property states that “the South of Market Area is the most sought after submarket in the United States for technology users and young working professionals.”
